From early November to late January, then from early April to late September, water the soil from one to two inches deep anytime it feels dry to the touch, giving it a good drink each time. Reduce watering to one a week from late January to early April and late September to early November.
Every four years, Christmas cacti must be repotted. Each time you repot your cacti, increase the size of the planter by two inches. If your cactus isn’t growing as quickly as you’d like, try placing it in a smaller container. Changing your potting soil may also aid in the growth of your cactus. Make a potting soil mix using equal parts sand, leaf mold, and commercial potting soil.
Water your Christmas cactus with an epsom salt solution to fertilize it. Mix one teaspoon of epsom salt with one gallon of water to make the solution. From the first week of April to the first week of September, apply this fertilizer once a month. You can also use a water-soluble all-purpose 20-20-20 fertilizer, which you can make by mixing a half teaspoon with one gallon of water and feeding once a month from April to September. You can alternate these fertilizers, but don’t use both at the same time and only feed once a month.
The temperature of the air, whether inside or outside your home, is also vital for your Christmas cactus to thrive. Maintain a temperature of 60 to 68 degrees Fahrenheit for your cactus during the fall and winter months. Cacti should be kept between 70 and 80 degrees Fahrenheit in the spring and summer, but never above 90 degrees Fahrenheit. During the fall and winter, holiday cactuses should not be exposed to more than eight to ten hours of bright light every day, as they require additional time in the dark to begin flowering for the holiday season.
How often do you water a Christmas cactus?
- Water every two to three weeks, but only until the top one-third of the soil feels dry to the touch. Water when the top 2 inches of soil feel dry, for example, if the plant is in 6 inches of soil. (Check with your finger!)
- Soak the soil until water runs through the drainage holes in the pot when it is suitably dry. To catch the water, place a tray underneath the pot. Remove any extra water from the tray after 10-15 minutes so that the pot does not sit in water.
- Feed every two weeks with a balanced houseplant fertilizer from spring through early fall. Feed the cactus once a month in the fall and winter to encourage blooming.
- Late in the spring, prune plants to encourage branching and more flowers. Simply cut a few portions off each stem, and the plant will branch out from the wound.
- Place the cut pieces in a gently wet potting soil if desired; they will root easily after a few weeks and make great Christmas gifts!
How to Get Your Christmas Cactus to Bloom
The lower temperatures and longer evenings of autumn bring out the blooms of Christmas cacti and its relatives. This is the general blooming schedule for the three main species of Christmas cacti:
- Thanksgiving cactus are the earliest and most persistent bloomers, blooming from late October to mid-winter.
It’s possible that your cactus isn’t flowering because it’s getting too much sunshine or being exposed to too hot temperatures. Here are some pointers to help you get yours to bloom!
- For at least six weeks, nights must be at least 14 hours long and days must be between 8 and 10 hours. If you have powerful interior lighting that is turned on at night, you may need to cover your cactus or transfer it to a location where it can be exposed to natural light.
- Flower buds form best when the plant is kept between 50 and 60 degrees Fahrenheit (10 and 15 degrees Celsius).
- By exposing the plant to temperatures of around 45°F (7°C) for several nights in a row, you can jumpstart the budding process.
- Ensure that you water the plant on a regular basis when it is in bloom. If the plant dries out too much, the buds may fall off.
- Don’t worry if the cactus loses its buds throughout the winter; it will bloom the next year!
How quickly do Christmas cactus grow?
Origin: Native to Southeast Brazil’s rainforests and coastal highlands; found in nature adhering to trees and rocks rather than growing in soil.
Growth rate and size: Within a few years, it can attain a spread of 2 feet. Cactuses for Thanksgiving and Christmas can endure for years, even decades.
Flowers: Fuchsia (the most frequent) and pink, red, white, or yellow are among the many colors available.
Toxicity: The fibrous plant material can cause gastrointestinal irritation in dogs and cats, but it is not poisonous to them.
Why is my Christmas cactus not growing or blooming?
Drought stress or too much light, as it is a short-day plant, are the causes of Christmas cactus not blooming. The Christmas cactus has evolved to thrive in humid, rainy environments. If it’s too dry or there are too many hours of sunshine during bloom creation, it won’t flower.
There are a number of other reasons that can hinder the Christmas cactus (Schlumbergera) from blossoming, which I’ve included below:
Continue reading to learn why your Christmas cactus isn’t blossoming, as well as the best methods and strategies for getting it to bloom…
Why is my cactus not growing?
The primary reasons for the cactus’ failure to grow include a lack of sunlight, overwatering, and the dormancy period. Give a cactus at least 5 hours of direct sunlight to revive it, and only water it if the dirt in the pot is absolutely dry. In addition, the room in which the cactus is grown must be well ventilated and have a moderate humidity level.
What’s wrong with my Christmas cactus?
A lack of water or too much direct sunlight can create wilted or limp Christmas cactus. If you haven’t watered the wilting Christmas cactus, start by giving it a small sip. Continue to water gently every several days until the soil is wet but not saturated.
Christmas cactus troubles are sometimes caused by damp soil. Because the Christmas cactus is an epiphyte that takes water and nutrients from the air in its natural habitat on the tropical forest floor, it cannot tolerate damp roots. Christmas cactus can become very limp because to poor drainage and damp roots.
If the leaves on your wilted or limp Christmas cactus appear to be dried or burnt, move it to a more shady location, especially in the afternoon.
How can you tell if a Christmas cactus is overwatered?
Although sagging, limp leaves and stems that are mushy at the bottom are strong indicators of overwatering and root rot, the only way to know for sure is to examine the plant’s roots.
How do you encourage new Christmas cactus to grow?
You can prune your plant after it has done flowering, around the end of the year, before new growth begins in the spring. You can prune your plant up to two-thirds of the way down. If you don’t think it’s overgrown, don’t bother about pruning it too much. A Christmas cactus’ stem nodes like interlocking puzzle pieces. Simply trim between the nodes of the stems using a sharp set of pruning snips. You can also twist and bend the nodes until they break off in pieces. I use the snips to keep the plant from being damaged.
You can also add fertilizing your original plant to your houseplant fertilizer program when it has finished flowering. Christmas cacti don’t require much fertilizer, but it can assist stimulate new growth throughout the year and increase blooming the next year. When watering, use an organic liquid fertilizer or sprinkle an organic granular fertilizer on top of the soil in the plant container.
Once you’ve taken your plant cuttings, dry them out on a piece of newspaper in indirect light for a few days before propagating them. The cut ends of the snips will heal and produce a callus as a result of this. You don’t want your clippings to decay, so keep them dry. You’re ready to start planting now.
How do you stimulate a Christmas cactus to grow?
- Use Miracle-Gro Cactus, Palm & Citrus Potting Mix to grow your Christmas cactus.
- To enhance blooming, give your Christmas cactus 6 weeks of increased darkness and cooler temperatures.
- To make new Christmas cacti, root the stem parts you trimmed off the plant.
Are coffee grounds good for Christmas cactus?
Your Christmas cactus will appreciate a cup of coffee just as much as you! Coffee grounds are high in potassium and nitrogen, which the cactus requires to stay healthy. You should not use the grounds right away since damp grounds can mold, so spread them out to dry first.
